IMPROVED FASTENR FOR STEKLIIJ'RIG" SPRINGS TO .BED-BOTTOMS AND MATTRESSES.

The Schedule referred to in these Letters Patent and making part of the Ilma.

Be it known that I, JOSEPH S. BARNUM, of the city of Topeka, and State of Kansas, have invented a new Vand useful Fastener, for locking spiral springs to the intersections of the steel strips in spring-mattresses,

Land, at the same time, for locking the strips at their intersection; and I do hereby declare that the following 1s a full, clear, 'and exact description of the con` struction and operation of the same, reference being lhad to the annexed drawings, making a part of thisV specication, in which- Figure l isaperspective view of the device reversed, or upper side down, in order to show the fastener more plainly. v

FigureV 2, perspective view ofthe fastener`A.

Figure 3, side View,- o1' longitudinal elevation of the astener A. Y

rlhis device. is for Securing rmly together the strips of hoop-iron, at the intersections of these in making up a spring-mattress, and also of securing to'thc Same place the spiral spring generally used for that purpose.

I construct the astener of a single piece of metal, having four arms radiating from its'centre, and two depressions, on its under side, crossing each other at right angles, MM, just wide enough to receive therein the intersection of two of the iron hoops, of which the mattress is composed, leaving at each corner, c c c c, a shoulder, a a a a, tting into eachof the four .corners of the intersectionv of" the hoops GC, D D.

Th'esefour shoulders form the end of the four arms of the fastener A. At two opposite angles, however, b Z1, the shoulders are extended so as to form a semicylindrical clamp, @which receives the coil of the spring, the groove c, in said clamp, having-its opening-,on the opposite Side of the fastener to that side above described.

The fastener A is placed over the intersection of .the hoops Where it is required to ax a Spring, the

hoops being placed above the spring.

The cross-depressions inthe fastener receive the intersection and. the cylindrical clamp b c, showing its opening upward.

The smallest end .of the spring is now passed beneath the hoops, and the end of the Wire passed through the cylindrical clamp c, again under the hoop, into the other clamp c, thus making a rnl lock together of the Spring to the intersection. i

A hole, or circular orifice in the centre of the fastener A, is for further securing the hoops to the same by means of the application of a punch to hoops over the hole, Where a smart bloisr will drive that portion ness of appliance.

What I claim as my invention, and desire to secure by Letters Patent, is

`The astener A, with its receptacles, il i i i, and shoulders, a a a at, and clamp, b c, and orifice, d, in its centre, as and for the purposes herein described.

JOSEPH S. BARNUM.
